The negative current collecting lead plate is welded to the bottom of the inner surface of the negative electrode case, but this method has poor workability such as positioning of the negative current collecting lead plate and insertion of spot welding electrodes into the holes of the spiral electrode. There are many processes. In the method (2) of spot welding to the side surface of the inner surface of the negative electrode case, welding of the negative electrode current collector lead plate has to be performed on the curved surface of the cylindrical negative electrode case, and reliable welding cannot be performed. As another method, there is a method in which the side surface portion of the outer surface of the spiral electrode is brought into direct contact with the inner surface of the negative electrode case without using a separator, but this method is not very reliable.

FIG. 1 shows a cylindrical battery of the present invention. In FIG. 1, reference numeral 7 denotes a spiral electrode in which a strip-shaped positive electrode and a strip-shaped negative electrode are wound via a separator. After inserting this into the negative electrode case 3, the negative electrode current collecting lead plate 5a is connected to the U-shaped aperture 3a of the negative electrode case.
To the part. Then, the positive electrode current collector lead plate 4a was spot-welded to the inside of the SUS positive electrode terminal 1 which had been integrated with the insulating gasket 2 made of polypropylene in advance. After injecting the electrolytic solution, bend the positive electrode current collecting lead plate 4a,
The positive electrode terminal units (1, 2) are placed in the opening of the negative electrode case, and thereafter the opening of the negative electrode case is swaged and sealed. Thus, the cylindrical spiral battery of the present invention can be manufactured.
